Each section is provided with a separate PTC resistance heating element and the two shell sections have different diameters and/or different bristles and/or at least one hair clamping arm. The handle is adapted to be selectively slipped onto either of the two shell sections, whereby at the same time an electrical connection is established between the heating element in the other shell section and an electrical power supply on the handle.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a heating device with a handle portion connected to a power source, and a device for mechanically attaching and detaching the curling iron and the handle portion and electrically connecting the same. This invention relates to a curling iron that can be heated electrically.

[Prior art and its problems]

West German Patent Publication No. 3,503,845 discloses an electrically heated curling iron having a heating device and a handle. The curling iron includes a handle that includes a connection that is mechanically connected to and disconnected from a power source to electrically connect the curler to the handle. Curlers of different shapes can be attached to the handle portion to meet the needs of different users. Since a heating element is attached to each curler itself, each of the curlers can be heated by electrically connecting the handle portion and the curler. However, since curlers that are not in use cannot be attached to the handle, they must be stored by some means, which is troublesome, especially when traveling.

Another problem for users is that the manufacturing and packaging costs for such curling irons are high. The electrical connections inside the handle of the curling iron described in Figure 1 of this disclosed West German patent are of a special shape suitable for devices using rechargeable batteries, and for safety reasons. Therefore, it is prohibited to connect the power supply device directly to a curling iron that is at least partially in operation.

Other structures of curlers that attach to curling irons are also known. This known curler has a structure that allows it to be slidably attached to a curling iron. This is to be able to respond to different requests of - users or different requests of multiple users. This type of curling iron is disclosed, for example, in US Pat. No. 3,918,465. However, a common problem with such curling irons is that the heat transfer between the heating element of the curling iron and a different curler that is slidably mounted is
It is usually not possible to optimize the temperature of each curler. Therefore, the temperature of the curlers cannot be set to the ideal temperature required for setting the hairstyle. In addition, since the curlers attached to this curling iron come in more than one type, they must be stored separately, which is also a burden for the user.

Also, a hair curler whose diameter can be varied in any way is known from US Pat. No. 3,583,409. Although this type of hair curler satisfactorily meets various requirements, it has a very complex structure and is expensive to manufacture. Furthermore, it is difficult to apply the principle of this hair curler to an electric heating type curling iron. The reason is that the construction of the heating elements incorporated into this type of hair curler is complex.

[Object of the Invention] Therefore, the present invention provides a curling iron that heats with electricity.
- The purpose is to improve the system so that it can fully meet the needs of individual users, has a simple structure, can be safely handled, and is easy to store. Another object of the present invention is to provide a curling iron that is compact and can be sold at a price that does not burden the user too much.

SUMMARY OF THE INVENTION The above objects are achieved by the electrically heated curling iron of the present invention.

The curling iron of the present invention includes two cylindrical parts, each of which is heated separately by two or more heating elements, and electrical energy supplied to the heating elements; , the heat generated from this heating element is supplied to the end of the curling iron, which is very convenient. In addition, since the curling iron can be partially stored inside the handle, it can be made extremely compact, reducing the storage burden on the user and reducing the burden of being careful to prevent parts from being lost. You can also eliminate the need to do so. At the same time, the electrical connection is connected only to the heating element of the curling iron. This connecting portion protrudes from the handle portion and is structured to supply electricity to the heating element of the curling iron, so this curling iron has a very simple structure and can be handled extremely safely.

Moreover, according to the present invention, an extremely compact curling iron can be provided. It has two different shapes
This is because by using individual cylindrical parts, it is possible to meet the needs of individual users. Since this handle part is mechanically and electrically connected to the end of the curling iron, the curling iron can be made to have a simple structure, easy to operate, and easy to store. At the same time, it can be made compact and inexpensive. Moreover, it is convenient to combine these cylindrical parts in various ways.

By simply planting bristles in both cylindrical parts of this curling iron and changing the diameter of this curling iron, the user can selectively change the size and tightness of curls.

Changing the diameter of the cylindrical part of the curling iron to form a micro-curler for special hair styles is very convenient, for example, for short hair styles. The user may also want to use an arm to clamp the hair. In that case, a curling iron with different diameters, ie, an arm that clamps the hair, is used with uncurved bristles. Additionally, the hair-clamping arm curling iron includes a slidable brush portion that can be slidably retracted into the handle portion when not in use. Additionally, the user may wish to alternate between wrapping the hair with the brush and wrapping the hair with the clamping arm. In that case, it is appropriate to have a curling iron with bristles planted in one part and an arm for clamping the hair attached to the other part. In the case of this structure, the two cylindrical parts of the curling iron may have the same diameter or different diameters. If the part of the curling iron where the hair-clamping arm is attached is made thinner than the part where the bristles of the curling iron are implanted, the user's hair will partially curl in the part where the bristles are implanted. This is especially useful when the is too short. On the contrary, when a normal user uses the hair-clamping arm to set the hairstyle, in order to curl the hair thinly or very tightly, the part where the bristles of the curling iron are planted is A combination that makes it thinner is preferable. In addition to these, although not listed here, various combinations can be made according to the user's preference, and these can be commercially available without any problem.

Another advantage of the curling iron of the present invention is that both ends of the curling iron can be heated with one heating element, and this advantage is achieved by appropriately disposing heat transfer plates to surround the heating element. This can be realized by

By positioning the heating elements between the heat exchanger plates so that they can be heated separately, the temperature distribution over the entire length of the curling iron can be adjusted to the special shape of the two cylindrical parts of the curling iron. A suitable temperature distribution can be achieved. A connection terminal for the heating element is provided in the center of the two head-side ends of the cylindrical part of the curling iron, and the connection terminal is attached to the connection member, and the curling iron and the handle are connected inside the handle part. When the parts are combined, the curling iron can be operated extremely safely by connecting the connecting member to the power plug located at the bottom part of the curling iron that is remote from the curling iron. . This is because the part to which voltage is applied can be kept away from the user. If a protective plate is provided at either end of the curling iron and the protective plate is moved by the force of a spring, when the curling iron is in use, the connection terminal of the above part of the curling iron can be Contamination can be prevented. Since the heating element on one part of the curling iron is connected to the connection terminal on the head side end of the other part of the curling iron, no voltage is applied to the exposed connection member of the curling iron. , Therefore, users can be safely protected. In another embodiment of the curling iron according to the invention, the electrical connection terminal in the central part of the curling iron is eccentric with respect to the longitudinal axis and connected to a corresponding connection member for connection to a power supply, It is placed at the end of the handle that is closer to the curling iron. With this structure,
The structure is simpler and therefore more economical to manufacture, and it also prevents the connection at either end of the curling iron from breaking and greatly reduces the possibility of contamination of the connection. can.

The curling iron has excellent manufacturing economy and safety in use by connecting the heating element and the connecting terminal using a link member made of conductive material and embedded in a separate indicator member. This can be ensured by electrically connecting the connection terminal and the screw-type connector.

The operability of the curling iron according to the present invention, especially when equipped with two hair-clamping arms, is excellent because the hair-clamping arms are provided in the center of the curling iron. This is because they can be operated separately by a single control member.

What is the cylindrical part 22?This first cylindrical part 21 and the second cylindrical part 22
The cylindrical portions 22 are fixedly coupled to each other. Since the first cylindrical portion 21 and the second cylindrical portion 22 of the curling iron 20 have basically the same internal structure, the second cylindrical portion 22 will be described below as an example. This second cylindrical part 22 houses a heating element 23, in particular a PTC resistor. This heating element 23 is sandwiched between electric heating plates 24.24 held in a chamber inside said second cylindrical part 22. The heating plate 24 engages the heating element, for example in a frictionally or play-free manner. The heating element 23 has a lead wire 25.25.

In the same manner as above, the first cylindrical portion 21°
A heating member similar to the above is provided inside the heating member, and this heating member consists of an intermediate plate member having high thermal conductivity and a lead wire 28.
28, and this lead wire 28 is connected to the second cylindrical portion 22.
extends to a connecting terminal 30.30 at the end 29 of the head. In the embodiment shown in this figure, the first cylindrical part 21 and the second cylindrical part 22 of the curling iron 20 have bristles 3.
It has 1°31,... The diameter D t of this bristles,
D2 is different. In order to electrically connect the connecting member 15, 26, the first cylindrical part 21 of the curling iron is slid into the diseased area 10, as shown in the figure. Electricity is supplied to the heating element 23 of the second cylindrical portion 22 . In this figure, the device for connecting the curling iron 20 and the handle portion 10 is, for example,
Either of the following two types of structures can be adopted. That is, the reference numeral 32 represents a fixing push button provided on the curling iron 20, and when the curling iron 20 is slid into the clasp 10, the push button 32 locks the diseased part 10. is fixed in the hole 34 of. Instead of such a structure, a latch 33.33. ... may be provided, and the latch 33 may be elastically engaged with a portion of an appropriate structure in the center of the curling iron 20.

In this example, the diameter of the second cylindrical portion 22 of the curling iron 20 is D2. If the diameter of the first cylindrical portion 21 is preferably Dl, when removing the handle from the curling iron 20, press the fixing button 32 or remove the handle from the curling iron 20. Push the end 29 of the head slightly and thus push the second cylindrical part 22 of the curling iron 20 into the diseased area 10. The first cylindrical part is heated by the connecting member 15° 30 and a heating element (not shown) of the first cylindrical part 21 having a lead wire 28 and is ready for use after a short time. become a state. The two cylindrical parts 21,22 of the curling iron 20 have completely different shapes, as will be explained in detail below. The embodiment shown in FIG. 1 is just one example of a variety of shapes. The dimensions of the two heating elements must be determined according to the two differently shaped cylindrical parts 21,22. In this way, the curling iron 20 can be heated to the optimum temperature regardless of its shape. Since no electricity is supplied to the exposed connection terminals 26.30 of the head-side ends 27, 29 of each of the cylindrical parts 21.22, the curling iron can be used safely.

FIG. 3 shows an end 27 on the head side of the curling iron 20.

The reference numeral of each part of this end on the head side corresponds to the first
The numbers are the same as those for each part in the figure. Curl iron 20 above
has a cup-shaped recess at its head end 27.29, which recess is in the immediate vicinity of the bottom plate-like member 40. Two bottle-shaped connection terminals 26, 26 are held on this bottom plate-like member 40, and a lead wire 25.25 extends from these connection terminals 26 to the heating element 23. It is located inside the second cylindrical portion 22 . The connecting terminal 26 engages a connecting member 15 in the form of a socket, which is connected to the supporting plate-like member 1 of the handle part 10.

D2 is different, and one of the cylindrical parts 21, 22 is provided with an arm 60 for clamping the hair, each arm 60 can be operated by one control member 61, and this control member 61 is It is attached to the coupling member 52 described above. This construction is extremely convenient for those who are accustomed to using traditional curling irons with hair-clamping arms. This structure changes the thickness of hair wrapping, or
This is useful when changing the degree of closeness of curly hair. The first cylindrical portion 21 has a small diameter D1 and can be conveniently used as a micro curler. This configuration requires the heating element to be dimensioned so that it can be heated in a very short time.

Furthermore, in some cases, the curling iron 2 in FIG.
It may be preferable to provide a brush with a sliding fit on the brush, ie of the slip-on type. In this way, the curling iron 20 can be made to meet the needs of individual users. Although not shown in the figure, the slip-on type brush has dimensions that match the width of the hole in the handle portion 10, and in this way, the brush can be inserted into the handle portion 10.
Similarly, sliding insertion is possible. When installing such a device, there is no need to provide additional space to accommodate the device when the curling iron is not in use, so it is compact, easy to carry, and easy to handle. It can be used for

A similar curling iron 20 is shown in Figure 4b.

This curling iron 20 has two cylindrical parts 21.22, which have a diameter D1. D2 is different. This cylindrical part 21.22 also has bristles 31.3.

Further, if one of the cylindrical portions 21 and 22 is formed into a micro curler having a built-in heating element of an appropriate size as required, other convenient structures can be formed depending on the situation.

Further, in the curling iron 20 shown in FIG. 4C, the first cylindrical portion 21 has a small diameter D1 and has a hair applying arm 60, and this arm 60 has an operating member 61. On the other hand, the second cylindrical portion 22 has a larger diameter D2 and has bristles. This construction is for users who use conventional bristled curling irons. Further, the first cylindrical portion 21 can set the hairstyle even when the hair is partially or entirely too short to use a conventional curling brush. Furthermore, by using a brush that is slidably inserted into the first cylindrical portion 21, it is possible to meet the special needs of the user. For users who wish to use a curling iron with hair-clamping arms in the same way as before, it is recommended to implant bristles into the thinner cylindrical part.
It is possible to provide a structure in which the thicker cylindrical part is provided with an arm for clamping hair.

For special uses, the cylindrical portions 21, 22 may be replaced with bristles 31, 31, . . . of the same diameter but different.
It is convenient to have a structure in which hair is flocked, or a structure in which an arm 60 for clamping hair and bristles 31, 31, . . . are combined.

FIG. 4d schematically shows the use of the curling iron according to the invention. Place the above handle part 10 on the above curling iron 20.
, and in this embodiment bristles 31.31. ...is planting. The dashed line in FIG. 4d indicates the second position of the handle portion 10. In this second position, the handle portion 10 is placed in the second cylindrical portion 22 of the curling iron 20.
This is the position where it is slid into place. In this state, the first cylindrical portion 21 includes the arms 60 that hold the hair, and is used.

Depending on the situation, in addition to the structure described above in which a heating element 23.50 is attached to each tubular section 21.22 for optimum temperature, one heating element may be used to heat both tubular sections 21.22.
It may be more convenient to heat 22. The heat transfer plate 24 is extended over the entire length of the curling iron 20, and a heat transfer plate is also provided at the connecting member 52. With this structure, the temperature of the two cylindrical parts 21 and 22 can be adjusted appropriately. This temperature adjustment can be carried out, for example, by attaching the one heating element to a suitable position inside the curling iron 20. moreover,
Such a construction requires the installation of an additional insulation device inside the handle portion 10. By adopting such a structure, the manufacturing cost of the curling iron described above can be further reduced.

FIG. 5 shows the control member 61 of the arm 60.60. This control member 61 is particularly convenient for operating the two hair-clamping arms 60.degree. 60 of the curling iron 20. FIG. 4a schematically shows a longitudinal section of the two tubular parts 21.21 of the curling iron 20. The cylindrical parts 21 , 21 have different diameters 1 and are connected by a coupling member, ie a joint 52 . The two hair-capturing arms 60.60 are rotatably mounted on pivots 70.70 of the edge portions 71.71 of the coupling member. This one hair-trapping arm 60 is connected to the pivot 70.7.
It is inserted at the position indicated by the symbol 72 in the middle part of 0,
Two finger-like extensions 73 , 73 extend along both longitudinal sides of the hair-trapping arm 60 . Either side of the arm 60 that clamps the hair of the other
The two pivots 70.70 taper sharply in the middle and the extension 74 engages the two finger-like extensions 73.73. Below the extensions 73, 74, inside the curling iron 20, there is a resilient member 75, which has a specific shape such as a spiral shape and clamps the material. The arms 60, 60 are pressed against the two cylindrical parts 21, 22 of the curling iron 20. On the side of the extension 73 , 74 remote from the elastic member there is a control button 76 .
The lower edge portion of 6 has opposing tabs 77, 77,...
·become. Two tabs 77.77 are provided on the sides of the control button 76, which has a sharp shape relative to the cylindrical portion 21,
This tab is located at the contact surface 78,78 at the end of the two finger-like extensions 73.73 of said one hair-trapping arm 60.
determine the position. On the side of the control button 76 opposite the two tabs 77, 77 there is another tab 77 which is connected to the extension 74 of the other hair clamping arm 60. Locate the contact surface 78 at the end. When the control button 76 is tilted toward either head-side end 27, 29 of the curling iron 20, this button 76 will move the two tabs 7 at that position.
7.77 is applied to the arm 60 clamping the mass, the two tabs 77.77 position the extension 73.73, and the arm 60 clamping the mass 60 engages the second cylindrical part 22. The arms which act together to clamp the mass move away from the second cylindrical part 22 in a direction opposite to the repulsive force of the resilient member 75. When the control button 76 is tilted in the other direction, the hair trapping arm 60 interlocked with the first cylindrical part 21 is separated from the first cylindrical part 21, and this movement causes the hair catching arm 60 to move away from the first cylindrical part 21. The force of the tab 77 is transmitted to the extension 74.

If the control button 76 is tilted to either side of its two operating positions, the elastic member 75 is compressed, and the other hair-clamping arm remains in the rest position. A slight gap is created in the arm where the elastic member clamps the other hair. This hair-clamping arm is therefore pushed slightly away from the tubular part. Such movement of the arm clamping the hair is based on the action of the arm clamping the other hair, and such movement of the arm clamping the hair is based on the internal structure of the handle portion 10. hindered by. The internal structure of this handle portion 10 is the same as that of the cylindrical portion 21.
．． 22 of the hair clamping arms 60 are suitably provided within the handle portion 10 to hold the hair clamping arms 60 in their respective tubular portions. Accordingly, the curling iron 20 is operated only by the handle portion 10 in the sliding position, so that during the use of the other hair-clamping arm, the arm 60 in the rest position
It can be completely prevented from being pushed out of its rest position. As shown in FIG. 5C, the extensions 73, 74
is approximately U-shaped, so that the arm 60. that clamps the mass is approximately U-shaped. It is possible to ensure sufficient rigidity of the lever-shaped arm of 60. Since the control member 61 for controlling the operation of the two hair-clamping arms 60, 60 of the curling iron 20 is in the form of a single control button 76, the curling iron becomes very easy to use. The structure is compact and can be operated reliably.

The structure of the pair of curling irons 20 explained above is as follows:
Further improvements can be made within the scope of the invention.
